I have a requirement wherein I need to convert the docx files to doc files. I looked around and found the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats ("http://www.microsoft.com/downloads/details.aspx?FamilyId=941B3470-3AE9-4AEE-8F43-C6BB74CD1466&displaylang=en"). Installing this would places a bunch of files in the C:\Program Files\Microsoft Office\Office12\ directory. This folder also contains an executable named "Wordconv.exe" which according to this http://www.oooninja.com/2008/02/office-compatibility-pack-review.html converts the docx files to doc files if you use the execute the following for example :-

"C:\Program Files\Microsoft Office\Office12\wordconv.exe" -oice -nme

I downloaded the compatibility pack and tried the above command. Nothing happens. No error message,no output,nothing. I wonder what is the problem. In the above link,some guys have suggested to download the latest windows updates from Windows.
Well,I tried this in my Windows XP 2nd Edition (with Service Pack 2) and only thing I am left to install in service pack 3. Is that required? This WIndows XP machine does not have the Office 2007 installed. Is it required?

Also,I tried this on a Windows server 2003 machine which also has the compatibility pack and result is same.

Am I missing anything? If yes,please let me know as I am kinda stuck in this. I dont want to use a commercial product like "Aspose.Words" for this.

Is there any other tool available from Microsoft to convert docx to doc files? Please let me know.
